Inapplicable mathematics, we are told, is perfectly thinkable, and systematic deductions, in themselves valid, may be made from concepts which contravene the facts of perception.
The practice of crossing, like that of close breeding, has its strong and its weak side. Judiciously practised, it offers a means of providing animals for the butcher, often superior to, and more profitable than, those of any pure breed. It is also admissible as the foundation of a systematic and well-considered attempt to establish a new breed.
It naturally ensues, from the absence or scantiness of explicit or systematic information connected with the opening stages of such inquiries as the present, that the student is compelled to draw his own inferences from indirect or unwitting allusion; but so long as conjecture and hypothesis are not too freely indulged, this class of evidence is, as a rule, tolerably trustworthy, and is, moreover, open to verification.
In the endeavour to reach this aim it is necessary that the examination of the child should be undertaken in a systematic manner, and that means should be adopted for the remedy of any defects.
The violent prejudice which previously possessed them, and the strong feelings of passion and fear which led immediately to their first systematic publications, must in the first instance awaken a suspicion as to their wisdom; and this suspicion becomes stronger when we find their writings different from the best of those which they profess to admire, and bearing a close resemblance only to those of the nonjurors.
German women, however, having proclaimed that they regard themselves liable for national service under the spirit if not the letter of the law, it has finally been decided to mobilise their services on a more systematic basis than in the past.
The discovery of the world divides itself into two branches the exploration of the globe, and that systematic exploration of the universe which is in fact what we call Science. Columbus made known America in 1492; the Portuguese rounded the Cape in 1497; Copernicus explained the solar system in 1507.
Nothing is more needed in our schools for both sexes than the systematic teaching of the principles here set forth; and we have no doubt this volume could be used as a text-book, at least with some slight omissions and additions, such as a competent teacher could well furnish. Portions of it, indeed, were some years since read by Mrs.
We sat down and had a long talk over this matter, and then we agreed to make a regular, systematic search through the woods, so as to make sure at least that you had not been killed. But now we thought of the difficulty of getting out of the cave without your help.
If not, hundreds and perhaps thousands of analogous cases are at once exposed to doubt, and the whole conception of systematic varieties would have to be thrown over. Biologists of course would have no objection to this, but the student of the flora of any given country or region requires the systematic subdivisions and should always use his utmost efforts to keep them as they are.
